Contractile vacuole in protozoan Amoeba is meant for

Step-by-step solution

Contractile vacuole is the clear rounded, pulsating body present in the posterior part of endoplasm of Amoeba. It is found only in fresh water forms and is mainly concerned with osmoregulation, ie, removal of excess of water. Plasmalemma, a trilaminar and selectively permeable membrane covering the body, functions both in excretion (ammonia) and respiration in Amoeba. Pseudopodia (false feet) are finger-like and blunt-extensions of cell body in protozoans. In Amoeba, the type of pseudopodium found in lobopodium, co
